GEORGE F. GODLEY, OF PHILADELPHIA, PENNSYLVANIA.

CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 451,195, dated April28, 1891.

Application filed February 18, 1890. Serial No. 340,857. (No model.)

To all whom it may concern:

Be it known that I, GEORGE F. GODLEY, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inCar-Axle Boxes; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has relation to car-axle boxes, particularly to the oilingdevices and the d ust shields thereof for the axle-journals; and it hasfor its object a simple and effective form of oiling device secured toor forming a part of the journal brass or hearing, and is operated bythe end-thrust of the axle to convey oil from the box to the journal.

My invention accordingly consists of the combinations, constructions,and arrangepnents of parts, as hereinafter described in thespecification, and pointed out in the claims.

Reference is had to the accompanying drawings, wherein Figure 1 is alongitudinal section of an axle-box with axle-journal in elevation,showing an oiling device and dustshield embodying my improvements. Fig.2 is a cross-section of axle-journal brass or bearing, boxoil-reservoir, and a modification of oiling device. Fig. 3 is alongitudinal section, partly in elevation, of the same. Fig. 4 is anenlarged sectional view of the form of oil-pump illustrated in Fig. l;and Fig. 5 is a sectional view of part of the axle-box with key for thebrass or hearing, showing the pumping devices secured to said key.

A represents an axle-box of any suitable form, which may, if desired, beprovidedwith a closed separate oil-reservoir a, located, preferably, atthe bottom of box A, or such bottom part of box A may of itself be usedfor holding oil.

B represents the brass or bearing for the axle-journal C, which brassmay be of any d material, and, as shown in ire-tin g front end 6, whichdepends in front of the axle, as illustrated, and is formed with achamber 1), in which is lo cated a pump-plunger, preferably hollow, ofany suitable kind, as indicated at d, and proas shown, if desired.

vided with an outer closed end projecting through chamber d for contactwith the end of the car-axle. In this hollow or tubular part of theplunger d an d abutting at one end against ashoulder or one of the wallsof chamber dis a reacting spring (1. From chamber 1) leads a pipe b thelower end b of which enters the box oil-reservoir, and is suitablyperforated,

From chamber 1) proceed other pipes or ducts 1), leading, preferably,through the brass orbearingB to a transverse or other suitably locatedrecess or recesses If on its under side, and which form oilchambers insaid brass or hearing B, contiguous with the axle-journal C, forlubricating said parts. In the endb of pipe 12 ,01- at any suitablepoint within its here, is located a ball or other suitable gravitysuction-acting valve 1). The end-thrust of the axle and the reaction ofspring 61 actuate plunger d to raise oil from chamber a to and throughchamber 1) and duct b to recess or recesses b. The depressed end Z) ofthe brass or bearing B also serves as a stop-bar for limiting theend-thrust of the axle, so that said brass, when constructed as shown inFig. 1, carries or is provided with said stop-bar and with an oilingdevice or pump which is actuated by the end-thrust of the axle. Thenthis construction is used, the end d of plunger cl may be made tubularand provided with a ball or check valve d with reacting spring d, asshown more plainly in Fig. 4., to admit of the 5 escape from chamber d,by the way of the hollow plunger and end-d of a small supply of oil forlubricating the end of the axle and those parts of the plunger d and ofthe brass or bearing B which cont-act therewith.

If desired, the projecting and depending front end 1) on the brassB maybe dispensed with, in which case the plunger d slides in asuitably-formed opening in the brass and has a bifurcated or recessedouter end engaging with the end collar 0 on the axle, and the pipe 6connects with the recess or recesses 12 in the brass B. (See moreplainly Figs. 2 and 3.)

From the foregoing it is evident that various constructions of pumpingdevices may be secured to or form part of the brass or hearing, andhence I do not limit myself to those shown and described.

The dust-shield for the rear end of the box may be of any suitableconstruction; but in the drawings I have shown the same composed of asheet-metal plate F, preferably of steel, having a central opening fsnugly fitting the axle, said central opening having preferably aflanged or upset edge to provide a suitable bearing-surface of the plateF on the axle. Said plate F is located between the usual or other doublewalls a a at the rear end of box A, or in a chamber a between saidwalls, or at the rear end of the box, said chamber a having preferablyan open top a. The plate F abuts against the rear face of the frontwalla, and between the vplate F and the front face of the rear wall a isa packing of any suitable material'such, for instance, as a plate ofwood, a layer of red fiber, felt, or other analogous yielding or elasticmaterial Ghaving a central opening to lit the axle. Said packingmaintains the plate F in position to seal it against the rear face ofthe front wall a, and also seals chamber a to effectually exclude dustand prevent the escape of oil from the box.

I do not herein claim the construction of dust-shield shown anddescribed, as the same forms the subject-matter of a separateapplication filed July 23,1890, Serial No. 359,656.

WVhen axle-box brasses or bearings are provided with a key H, as shownin Fig. 5, the pumping devices may be secured to said key, as indicated;and my invention comprises the same, as said key is in effect a part ofthe brass or bearing, or said key may be a part 5 of the top of the box.

What I claim is 1. I11 a car-axle box, the combination of an in saidfront end of the brass and actuated by the end-thrust of the axle,substantially as set forth.

3. An axle-box brass or bearing having a projecting and depending frontend forming a stop-barfortheendofacar-axle,andoil-pumping devicesattached to said brass end and actuated by the end-thrust of the axle,substantially as set forth.

-;t. An axle-box brass or bearinghaving projecting front end I), achamber bin said end, a plunger with reacting, devices in said chamber,a pipe 6 with check-valve, depending from said chamber, recess orrecesses Z) on the under side of said brass, and duct b connecting saidrecess with chamber Z), substantially as set forth.

5. In combination with an axle-box brass or bearing, a hollowpump-plunger containinga reaction-spring and operated by the endthrustof the axle, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE F. GODLEY.
